“…For these reasons, a number of studies have recently focused on the development of metastable β-type Ti alloys with non-toxic elements such as Mo, Zr, Sn, Ta and Nb [14][15][16][17][18][19][20][21][22][23] .…”

Beta titanium alloys were developed for biomedical applications due to the combination of its mechanical properties including low elasticity modulus, high strength, fatigue resistance, good ductility and with excellent corrosion resistance. With this perspective a metastable beta titanium alloy Ti-12Mo-13Nb was developed with the replacement of both vanadium and aluminum from the traditional alloy Ti-6Al-4V. This paper presents the microstructure, mechanical properties of the Ti12Mo-13Nb hot swaged and aged at 500 o C for 24 h under high vacuum and then water quenched. The alloy structure was characterized by X-ray diffraction and transmission electron microscopy. Tensile tests were carried out at room temperature. The results show a microstructure consisting of a fine dispersed α phase in a β matrix and good mechanical properties including low elastic modulus. The results indicate that Ti-12Mo-13Nb alloy can be a promising alternative for biomedical application.

“…Several promising metastable b-type Ti alloys have been developed for orthopedic implants such as TieZreNbeTa, TieNbeZr, TieSneNbeTa, TieSneNbeTa, Ti-Mo-Nb and TieNbeTaeMo [2e5,17e19] and, for these alloys, Young's modulus varies between 50 and 95 GPa due to the alloy composition, thermomechanical treatments and a bi-phased (a"þb) microstructure [3,10,12]. Studies show that it is not trivial to obtain low Young's modulus and high strength simultaneously in Ti alloys [14].…”

A low Young's modulus is required for titanium alloys used in orthopedic implants, such as hip prosthetic stems, in order to avoid stress shielding due to a large difference in Young's modulus between the prosthetic stem and the cortical bone. The low Young's modulus has been observed to occur in metastable b-Ti alloys by precipitation of a stress-induced a 00 martensite during cold deformation. Under this context, the Influence of thermo-mechanical processing on the microstructure and mechanical properties of the metastable b Tie29Nbe2Moe6Zr alloy was studied as well as the influence of the degree of deformation by cold rolling with subsequent annealing after homogenization heat treatment. The alloy presents a b microstructure after solution heat treatment at 1000 C for 24h, followed by water quenching, while posterior cold rolling induces the precipitation of a" martensite. Young's modulus decreases and hardness increases with the degree of deformation. The annealed samples showed higher hardness and Young's modulus than the cold rolled samples. A thickness reduction of 90% maximizes the hardness/Young's modulus ratio and optimizes the required mechanical properties for orthopedic implants. The results indicate that the alloy is a promising alternative for the widely used Tie6Ale4V.

The corrosion behavior of Ti-5Ag-xFe alloys (x ¼ 1, 2.5, 5 wt%) in neutral saline solution was investigated by the open-circuit potential (OCP), potentiodynamic polarization, electrochemical impedance spectroscopy (EIS), and potentiostatic tests. The microstructural observation indicated that b-Ti phase was retained by the addition of Fe into Ti-Ag alloys. Compared with commercially pure (CP) Ti, Ti5Ag-xFe alloys exhibited higher corrosion potentials, lower current densities, and larger impedance, these suggested that Ti-5Ag-xFe alloys have nobler electrochemical corrosion behavior when compared with CP Ti in neutral saline solution.
